R Series Truck Diesel Engine

Our R series truck diesel engine is newly developed product after we join Shanghai Automotive Industry Group. It works at high rotating speed with low displacement, meeting the requirement in the emission standard of China IV and the future China V. As this product introduces the mature European parts, it features high reliability, extensive application and sophisticated manufacture.

The product is widely applied in various vehicles in great demand in the world including the middle and high end light duty truck, Chrysler, Land Rover, Cherokee and so on. With the development of the auto market in China, the R series truck diesel engine becomes the preferred power for many domestic diesel vehicles.

Detailed Information
Technologies Function Advantages
16-valve cylinder cover Increase the inlet flow Improve the engine performance like horsepower and torque.
The second generation BOSCH high
pressure common rail fuel system, CP1H oil pump		 It can spray five times each cycle and the maximum fuel injection pressure reaches 1600bar. The flow deviation of the fuel injector can be controlled. The engine performs with lower emission, noise and fuel consumption for
Optional VGT/FGT supercharger with electronic control and variable cross
-section 		The R series truck diesel engine gets wider torque and faster dynamic response. The driving performance and the economical property of the vehicle are improved. The emission and fuel consumption become lower.
Tappet roller pin Reduce the height and friction loss for the engine The engine becomes small in size and it reduces the fuel consumption.
Hydraulic gap adjuster Automatic adjustment for the valve clearance The maintenance is easy to be accomplished without adjusting the intake and exhaust mechanism.
Common rail pressure control valves Better control for the common rail pressure Improved the drivability of the vehicle and the stability of the cold start and the engine operation
DOHC (Double overhead camshaft) Increase the coolant and air flow rate and improve
the engine performance		 The engine power is improved
